Add smoke tests for a selection of iCE40, ECP5, Xilinx, Intel boards.

The purpose of these tests is just to ensure that Amaranth changes do
not blatantly break the boards repository. They are not intended to
exhaustively test even a single board.

Everything Gowin-related is removed due to Apicula's problematic use
of numpy.
